As you squeeze the bottle, the system expresses the increase in pressure by compressing the air column and pushing the water towards the capped end of the pressure indicating tube.

I chose to measure the situation in mm because I don't think that the water will move drastically in the pressure indicating tube, so therefore I would like to be able to be most accurate.

27.3cm
Initially I began measuring in mm, but found it too difficult to determine the change to that precision, so I had to go back and measure in centimeters so that I was more confident with my estimations.

The first is the distance from water level my mark lies, the second is the original air column position, the next lines are the initial positions and final positions of my pressure experiments.

Good data. This will provide a good basis for the next experiment.
